Study summary

This is a cluster randomized trial to evaluate the effectiveness of integrated care centers (ICC) to improve access to HIV testing, prevention services, and treatment among high-risk populations of injection drug users (IDU) and men who have sex with men (MSM) in India. We will collect baseline ethnographic and survey data from approximately 27 IDU or MSM sites in India. We will use baseline data to select 22 sites for the trial (12 IDU and 10 MSM) and to stratify sites according to key baseline characteristics. We will perform stratified randomization to assign sites to either the ICC intervention or to standard services. ICCs, which will be either IDU or MSM-focused, will provide an accepting atmosphere in which members of vulnerable groups can drop-in, receive rapid HIV voluntary counselling and testing, risk reduction counseling and services, and antiretroviral therapy. ICCs will be scaled-up from existing governmental or non-governmental organizations and services provided at ICCs will be supported by the National AIDS Control Organization (NACO) of India. After providing services in communities for two years, we will conduct an evaluation survey (with biological and behavioral measures) of approximately 1000 subjects in the target populations in each of the 22 study sites. Integrated care centers have the potential to improve access to HIV prevention and treatment services among vulnerable, high-risk populations.

Study arms

  • Experimental
    Integrated care centers

    Integrated care centers will provide HIV prevention and treatment services to high risk populations of IDU or MSM in an accepting and supportive environment. * HIV voluntary counseling and testing \& staging * Risk reduction services including free condoms, needle and syringe exchange, opiate substitution therapy * Substance abuse counseling * Sexually transmitted infection screening and treatment * Access to free antiretroviral therapy and adherence support * Peer community outreach

    Behavioral: Integrated care centers

  • No intervention
    Standard services

    In Standard Services sites, HIV testing, prevention, and treatment services will be available through standard venues. Government centers typically provide most HIV testing services and are the only source for free antiretroviral therapy. Non-governmental organizations typically provide prevention and risk reduction services.
